I understand how you use it, but if you absolutely want to use it that
way, then you should ensure that your frontend contains a rule which
prevents the use of the faulty backend once it's down.
For instance :
frontend pub
use_backend all_down if { nbsrv(bk_www) lt 1 }
default_backend bk_www
backend bk_www
errorloc303 xxx
server s1 ...
server s2 ...
server s3 ...
backend all_down
# no errorloc, no server, the user will get a plain 503.
# Alternatively, an errorfile might be used to return
# something cleaner.
